TO ALL WHOM ET MAYCONCERN: n t

Be it known that I, FRANCIS H. Duc, of Charleston, in the district ofCharleston, and State'ot South Carolina, have invented a new andirilproved Ice-Cream Freezer; vend I do hereby declare thnt thefollowing is a full, clear,- and exc-et description thereof, which willenable others skilled in the art to make and userthe same, referencebeing'had to the accompanying drawings, forming part of thisspecifica-tion, nhich- Figure 1 represents a longitudinal verticnlsection of my improved ice-cream` frcezershowng it while it is beingfilled, i t

Figure 2 is a similar vier/showing itin working position'. v t Figure 3is a vertical cross-section ofthe latter, the plane of section beingindicated by the line :v as, fig. 2l. Similar letters of referenceindicate corresponding parts. t This invention relates to a. new devicefor freezing' ice-cream, and consists in the use of a revolvingcylinderd, in which the cream is held, said cylinder being fitted arounda stetoriory'shnft, which `carries o wing for feeling or indicating thestate of the contents; Ail the parts constituting this device can betaken apartfcr cleaningA andother purposes. The cylinder is fitted inabox, yin which it has its bearings,an=l in which it is fittedvertically when to be filled, and horizontally while being turncd. l

A represents e box, made of wood cr other suitable materiel, ofsuiiicicnt size, and of rectangular or other suitable form.A Itis, ormay be, supported upon legs B B, of suitable height, and is providedwith a. hinged cover, C, as shown. D is n, cylinder, made of sheet metalor other `suitable material, having' conicalfheeds, :is shown in fig. 2.One of these beads E is screwed upon lthe cylinder, and canbe unscrewedfromthe saine, as in fig. 1. Through the opposite fixed head passies ashaft, F, whichfcarries a perforated wing, G, as shown; A smiling-box,H, keeps the joints around, the shaft F closed. On the extreme end ofthesheft F isa.V handle, by which it can bc turned, On the removableheed E isA a criink, T, by whichthe whole cylinder can hcturned.` A holeis provided inv the centre of che cover C of the box A large enough toallow the cylinder to` be passed through it. A ilcngeon the latter restsupon the cover, and lits over two or more `pins a thutare provided inthe cover to prevent the cylinder from turning. The coveringr head E isthen unscrewed fromthecylinder, as 1in fig. 1, ond the same can be lled.When the cylinder is filledthe head E is screwed down agnimcnd thecylinder is taken out of the box A. The cover of the latter is opened,and the cylinder placed into it in alori- .rental-position, thecylindrical ends of its heads sliding down in recessespi'ovitlcdfor'that purpose in the ends of the box,l whiclirecesses areclosed, after the cylinder is inserted, by means of sliding plates b, asshown (partlykin dotted lines) in iig. 3. Ieeis then packed into theboit A, so as .to surround` thetoylindeq the'eover C is let down, andthe holein its centre is `closed by a. suitable plaie, K, (figs. 211ml`The cylinder is ,then revolved by means of the crank T. Theshnft F isnow and then turned, by means of the handle I, to ascerteein lthccondition of'. the contents of the cylinder, When it is very hard toturn it is a sign thatthe creamis froze-11 es the wing G meets with moreresistance; and, when the cream is suliiciently frozen,` the cover Cisopened, the cylinder taken out and replaced into the Averticalposition, as shown in ig.- 1', the head E is unscrewed,V and 't thecontents are removed.v The shaft F can then be' easily drawn out, andthe whole be cleaned withfacility.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is` 1. 'The revolving cylinder D, whenprovided with the removable head E, shaft F, and wing` G on the letter,p

f the said shaft ond wing serving as an indicator for nscertoiningtliestate of the contents, substantially ns herein shown and described.

2. The above, in combination with the box A, havings` a hinged cover, G,in which another central cover, El, isarranged, substantially as and forthe purpose herein shown and described.. l
